Armed police have arrested a man on suspicion of shooting a father of four to death during rioting in Croydon.

Officers investigating the killing of Trevor Ellis, 26, carried out an "armed operation" in Camberwell, south-east London, where they arrested a 24-year-old. He was later released on bail.

Mr Ellis, of Brixton Hill, south London, was found with bullet wounds in a car in Croydon last Monday.

Police think he and some friends had a row with a group of about nine people.

'Violence and disorder'

Three other men have been arrested over the murder, which is thought to have happened following a car chase beginning in Scarbrook Road, Croydon, and passing along the A232 flyover into Duppas Hill Road.

Police appealed for information about the pursuit involving a dark coloured estate car and silver hatchback - believed to have been driven by the group of nine - and a dark coloured hatchback in which Mr Ellis was a passenger.

Mr Ellis was found shot at about 21:20 BST on the corner of Duppas Hill Road and Warrington Road.

A post-mortem examination showed he died from a gunshot wound to the head.

On Sunday, Det Ch Insp Neil Hutchison, who is leading the investigation, said: "Trevor Ellis was murdered on a night where Croydon, and in fact London, saw unprecedented levels of violence and disorder.

"I believe his killers were actively involved in looting and responsible for robbing at least two people that night.

Released on bail

"They thought nothing of arming themselves with a gun and ultimately taking a young man's life, leaving four young children without a father."

On Saturday afternoon a 27-year-old man became the third person to be arrested on suspicion of Mr Ellis's murder.

He has also been released on bail until September.

A 26-year-old man arrested in Mitcham, south London, on Friday, and a 24-year-old man arrested in Brighton, East Sussex, on Thursday have both been bailed until mid-September.
